APPARATUS FOR THE LIQUEFAGTION OF AIR.

Serial No. 303,129.

T 0 all whom it may concern:

Be it known that I, GEORGES CLAUDE, manager of La Socit lAir Liquids,residing at Paris, France, t3 Rue St. Lazaro, have invented certain newand useful Improvements in A paratus for the Liquefaction of Air, ofwhic the following is a specification.

This apparatus is composed principally of two series of tubes located ina vessel containing liquid air or oxygen. of tubes is supplied with coldair under pressure, which air becomes partially liquefied therein, andthe residual gas escaping therefrom issubsequently liquefied in thesecond series of tubes.

In the accompanyingillustration I have shown by way of example adiagrammatic view of an'apparatus embodyingmy present invention.

The apparatus consists broadly of a series of tubes A in communicationuitli a lower collector B and an upper collector C: and of coldcompressed air by one of the lower collectors, as B. This air in risingin the part A becomes partially liquefied and tho liquefied portionfalls into the collector Bffrom which it is drawn oil to the exterior toserve "the uses to which it is desired to put it.

In conformity with the process of partial liquefaction, as abovedescribed, this liquid portion which collects in B consists of a Thefirst series -is.to say into the series of tubes l), where it becomesliquefied and falls into the collector E. The li uid poor in oxygen,collected in E for emp oymcnt in accordance with requirements may, ifthe conditions are favorable, that is, length of tubes in the series Aand D considerable, and the elocity of the gas small, be composed ofalmost pure nitroen. What I claim and desire to secure by Letters Patentof the -United States is:

An apparatus for li uefying air, comprising a series of upr ght tuoes, achamber at the upper end of said tubes and in communication therewith, areservoir for collecting air liquefied in said tubes, means to admit airunder pressure to said tubes, a second series of upright tubes incommunication with the said upper chamber, a reservoir adapted tocollect air liquefied in said second series of tubes and meanssurrounding said tubes adapted to maintain a refrigerating agent incontact therewith, substantially as described.

In testimony whereof he afl'ixes his signature in presence of twowitnesses.
